Technical field
The utility model relates to a kind of auxiliary equipment that is used for explosion, particularly a kind of equipment that is used for the stemming moulding.
Background technology
Stemming is to be used for the material of plugged perforation; The quality of stemming and be shaped quality, sealing clay length and sealing quality etc. directly influence demolition effect and safety.
Stemming mainly is the demolition effect that can improve explosive, increases a resistance of mouth, makes and builds up the compression ability in the borehole; Improve the impulsive force of shock wave; Stop the detonation gas of high pressure to release certain applications, can also make explosive fully oxidation in explosive reaction simultaneously, emit more energy from the borehole spray; Make heat fully be converted into mechanical energy, thereby reach desirable demolition effect.Simultaneously, guarantee shotfiring safety, the temperature and pressure when reducing detonation gas effusion working face; Also because stemming can stop flame and scorching hot solid particle in borehole, to spray, reduced the possibility of the gas that ignites, coal dust simultaneously.
Stemming need be processed strip before putting into borehole, in the prior art, mainly is to pinch shaping through artificial hand.Hand is pinched shaping not only increases operator's labour intensity, reduces operating efficiency, and the stemming after being shaped is different, and size criteria is different, encapsulates unreally, in the process of blowing out, is prone to naked light, has very big potential safety hazard.For overcoming the above problems, Stemming machine has appearred, have high efficiency, result of use is better.But common Stemming machine has bigger volume and weight, needs bigger drive energy, uses and keeps in repair very inconvenience, and operating cost is higher.
Therefore, need improve, alleviate operator's labour intensity, increase work efficiency, make the unified size that has standard after the stemming moulding simultaneously, have effect preferably, have smaller volume and weight existing stemming moulding means, easy to use.
The utility model content
In view of this, the purpose of the utility model provides a kind of stemming shaped device, during use; Alleviate operator's labour intensity, increase work efficiency, make the unified size that has standard after the stemming moulding simultaneously; Have effect preferably, have smaller volume and weight, easy to use.
The stemming shaped device of the utility model, comprise body and with the interior piston that is slidingly matched with it in the body that is placed in, said piston is provided with and is used for driven plunger along body pistons reciprocating bar.
Further, also comprise the driving tracheae that is used to connect high-pressure air source, the gas outlet of said driving tracheae is communicated in body and is positioned at the actuator chamber that piston tail forms; Said body tail end sealing, the piston rod tail end sealing passes the tail end of body;
Further, also comprise triple valve, said triple valve is provided with air inlet, exhaust outlet and porting, and said porting is communicated in actuator chamber, and air inlet is communicated in the gas outlet that drives tracheae;
Further, said body afterbody is provided with and controls handle;
Further, it is forming cavity that said body is positioned at the anterior cavity of piston, and said forming cavity is positioned at tube body wall and has bar shaped steam vent longitudinally, and the longitudinal length of said bar shaped steam vent is less than the longitudinal length of piston;
Further, tube body wall outer round surface front end closes up to the center and forms circular cutting edge;
Further, said piston rod passes the body tail end and is provided with driving handle.
The beneficial effect of the utility model is: the stemming shaped device of the utility model, adopt the piston type building mortion, and utilize the plasticity of stemming itself, be the mould direct forming with the body; And, alleviate operator's labour intensity by piston release use, and be shaped rapidly, increase work efficiency; Make the unified size that has standard after the stemming moulding simultaneously, have effect preferably, and the utility model is simple in structure, volume is little; And the shaping operation method is simple, and is easy to use flexible, practices thrift cost.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the triple valve structure principle chart.
The specific embodiment
Fig. 1 is the structural representation of the utility model; Fig. 2 is the triple valve structure principle chart; As shown in the figure: the stemming shaped device of present embodiment; Comprise body 1 and with the interior piston 2 that is slidingly matched with it in the body 1 that is placed in, said piston 2 is provided with and is used for driven plunger 2 along body 1 pistons reciprocating bar 2a.
In the present embodiment, also comprise the driving tracheae 5 that is used to connect high-pressure air source, the gas outlet of said driving tracheae 5 is communicated in body 1 and is positioned at the actuator chamber 1a that piston 2 afterbodys form; Said body 1 tail end sealing, piston rod 2a tail end sealing passes the tail end of body 1, and sealing means can adopt multiple structure, such as sealing gasket, O RunddichtringO etc.; During use, body 1 front end is directly inserted the stemming raw material, utilizes the pressure of stemming that piston 2 is retreated, but simultaneously also manual drives piston rod 2a piston is retreated, stemming is a die forming with body 1; To drive tracheae 5 and be communicated in gas cylinder, through drive of high-pressure gas piston 2 forward, the stemming that is shaped released in body, promptly accomplish a forming process.
In the present embodiment, also comprise triple valve 4, said triple valve 4 is provided with air inlet 4b, exhaust outlet 4c and porting 4d, and said porting 4d is communicated in actuator chamber 1a, and air inlet 4b is communicated in the gas outlet that drives tracheae; When piston 2 is retreated, rotate the spool 4e of triple valve 4, make spool 4e channel alignment exhaust outlet 4c and porting 4d, air inlet 4b sealing is accomplished exhaust thereby actuator chamber 1a is communicated in exhaust outlet 4c through porting 4d; When piston 2 need advance, in air inlet 4b and porting 4d, gases at high pressure got into actuator chamber 1a with the spool 4e channel connection of triple valve 4, and driven plunger 2 is advanced, and use is simply laborsaving.
In the present embodiment, said body 1 afterbody is provided with controls handle 3; It is stable convenient to control during use, is beneficial to further reduction and uses difficulty.
In the present embodiment, it is forming cavity 1b that said body 1 is positioned at piston 2 anterior cavitys, and said forming cavity 1b is positioned at body 1 wall and has bar shaped steam vent 1c longitudinally, and the longitudinal length of said bar shaped steam vent 1c is less than the longitudinal length of piston 2; Be beneficial to stemming and fully fill up forming cavity, avoid occurring forming defects, and not with actuator chamber 1a in gas disturb.
In the present embodiment, tube body wall outer round surface front end closes up to the center and forms circular cutting edge; Insert stemming when being beneficial to operation, further reduce labour intensity.
In the present embodiment, said piston rod 2a passes body 1 tail end and is provided with driving handle 2b, is beneficial to through hand assisted, makes this device have operating flexibility.
Explanation is at last; Above embodiment is only unrestricted in order to the technical scheme of explanation the utility model; Although with reference to preferred embodiment the utility model is specified, those of ordinary skill in the art should be appreciated that and can make amendment or be equal to replacement the technical scheme of the utility model; And not breaking away from the aim and the scope of the utility model technical scheme, it all should be encompassed in the middle of the claim scope of the utility model.
